SUMMARY:Scale invariance\, a hidden symmetry explored with quantum gases -

CONTACT:Dr Nur Unal
DESCRIPTION:Scale invariance\, a concept initially introduced in high-ener
 gy physics\, has gained numerous applications in the physics of quantum fl
 uids. It can be used to describe strongly interacting Fermi gases\, two-di
 mensional Bose gases\, as well as few-body systems that exhibit the "Efimo
 v effect." This presentation will demonstrate how scale and conformal inva
 riance emerge in cold atomic gases. Examples will be provided from a range
  of fields\, including thermodynamics\, soliton physics\, and specific str
 uctures with periodic time evolution\, known as "breathers".
